Question about Televison & Video
Once warmed up the picture disappears completely then it goes into some sort of color cycle test where the complete picture goes blue, then white, then green, then red. This pattern cycles continuously. The sound remains ok. Turning the set off then on may bring back the picture for a short while, but generally it stays in color test mode
SOURCE: Insignia 26" cycles colors
This is a problem with the switching circuit on the television. The color cycling is a service test pattern for checking the operation of the color circuits on the television. This could be as simple as a cold solder joint on the circuit board or crosstalk on the circuit board or wiring causing the problem. It also could be a problem with a faulty component or the switching control IC. This should be tested in a service center to isolate the problem. The service number for Insignia is 1-877-467-4289. Hope this helps you with your problem. The second problem is not the same as the vertical lines are another problem altogether . This unit need to check for faulty components at a service center. Please call the above number for technical help with you problem. Hope this helps you with your problem.

Most likely you can adjust it in the Service Alignment Mode (SAM).
Press 062596 followed by the STATUS button (upper left). Navigate to "White Tone", press the right key to enter and select "Normal" mode. Set the colors:
Red = 135, Green = 128, Blue = 133.
The "Cool" and "Warm" menus are deltas from the "Normal" settings:
COOL: R -3, G -1, B 5
WARM: R 2, G -3, B -13
Press the "MENU" button to return to the main menu, then the "Power" button to turn the TV off.

Power supply is the place to look, look for bulging on top of the capacitors in the secondary side of the main power supply.

This could be a reception problem of the cable transmission or the cable box if used. Are you using cable or SAT box. Tv goes to blue screen if signal is weak automatically.
